Allomey WITNESSES ROBERT:.& HOUSTON, OF CLAIBKS'ION, WASHINGTON.-

To all it may concern: i

Be it known that I, ROBERT A; Hdos'rori,'

a citizenof the United.States, residing at Clarkston', inthe, countyxof "Asotin and:

State of vi ashing'ton, have invented new and useful Improvements inEmerg'ency-Brakes 'gr teeth 'if 'des1r'ed pr'e rent any "slippfi'gmfi for Automobiles, of which. the'following is his invention relates to an emergency brake for automobiles andother vehlcles,

. and more particularly to a brake which is tion is to provide snnp used only occasionally or to avert accident and under ordinary conditions the usual form of brake will be employed to check the forward movement of the machine.

The primary object of the. present invenle and eflicient means whereby in case there is a possibility of an accident, or for other reasons, the progress of an automobile or other vehicle may bereadily and quickly checked by raising the i driving wheels of thevehicle from the ground and thus permit the engine to rotate the driving axle and wheels of the'vehicle with-v out resulting in a pro 'ulsion of the latter.-

the present invention is to provide an' emergency brake for automobiles, as before described, which will be inexpensive to manufacture, strong, durable and eflicient in useand automatically opereted from'the drivers seat. a v

Other objects will appear as the description continues.

With the above and other objects inview, this invention consists of the novel construction, combination, formation and arrangement of parts as will be hereinafter more fully described, claimed and particularly pointed out in the appended drawings, in which Figure 1 is a side elevation of the improved emergency brake embodying my invention as applied to an automobile, Fi 2 illustrates my invention when in'use an as applied to the rear portion of an automobile, and Fig. 3 is a lan view of my invention as applied to the i rame of the automobile.

- eference' now being had to the accomanying drawings, wherein like parts are inicated by like references throughout the several views, the numeral 10 indicates-the usual bed -r frame of an ordinary automo-' bile which is supported by the usual wheels 11. Suspended from the rear axle 12 of the r automobile adjacent the rear driving wheels is a pair of supporting members 13. These answerer-Beans roe auron'onmas.

the same. Secured to-th'e central portion oi the front axle 16 is a pair of rear'wardly extending? supporting members-areprovidediatvone endim with fj a sleeve 14' which-is 1 loosely mounted" le' 'of ithe vehicle and chains 17 whiclrare connected adjacent ment of the supporting members to and hold the supporting members in a substantially. vertical position when the emergenc brake has been a wplied and also relieve t 10 con necting ro 19,-which will be hereinafter described, from any-strain.

, ltfountedtransversely (ff the vehicle frame is a rock shaft'20vhaving mounted on oneextremity thereof a crank 2 1which is connectedto one ofthe supporting members 15. rod 19 and the opposite ex by a connectin tremity of sai rock shaftis rovided with a double crank22,' 'one end 0 which is connected to the opposite supporting member 15 by a connecting rod'19.L:---

Pivotally mountedfadjacent the drivers seat is a lever 23 which is connected to the opposite extremity of the double crank 22 by meansof a rod 24.- TIt' is obvious that when this lever is thrown in a forward direclower' extremity of the supporting-g member) 15 as at 18. These claims limit the move-"- tionit will cause the supporting members e ground, thereby holding the rear portion of the vehicle in a'raised position. Extending from each of the cranks 21 and 22 are coiled springs 25 which are connected to the chains 17 which will normally hold the said chains in-a raised position, as shown in Fig. 1 when the brake is not in use to prevent the same from dragging along the ground or coming into contactwith any'movmg objects. It is apparent from thezforeglomg descripthe accom- 'panying drawings, that I have provided an emergency brake for automobiles which is positive in action when stop ing the vehicle much more uickly and readily than can be accomplishe by the brakes as ordinarily constructed without necessitating the stop-- page of the motoror en ine. It is to be understood further that otlier minor changes in proportions,dimensions and details may be resortedto without departing from the spirit oifthe present invention but which comeyithintho the a pended claim. Havin thus fully describe my invention,
